I know you have fielded this request multiple times, but I wanted to make an official feature request for a Mac-based editor.
The iPad editor is great for small tweaks, but less so for batch editing of controls and quick rearrangements of your layouts. What I envision is a Photoshop like editor, with an inspector of sorts, that would allow you to create groups of objects and edit multiple parameters at once. For example, let's say I have a page with 50+ controls o them, and I decide I want them all to respond to MIDI channel 4. A quick "Command A" select all and hop over to the inspector to set the MIDI channel.
There is so much flexibility in your product, but designing complex layouts can be rather inefficient. I, for one, would pay another fair fee for access to a desktop editor, from which you can port your creations over to the iPad. Furthermore, the having the usual suspects of a graphic design or vector program such as "distribute vertically/horizontally" or "align top/middle/bottom" would be a Godsend. Thanks!
